When Mendel performed di-hybrid crosses (i.e. pea color and pea shape) what did he find in the F2 generation?     He found that traits were linked together, such that if an individual was homozygous recessive for 1 trait it would also be homozygous recessive for the other trait     He found a set of intermediate phenotypes in the F1 and F2 generations for each trait     He found one trait could return in 25% of the offspring but the other trait did not     He found that each trait was inherited separately from the other trait, indicating that traits are randomly assorted

In the Pea plants studied by Mendel, green pod colour is dominant over yellow pod colour. You have grown the same species in your garden and the plant is producing only green pods. You were guaranteed by the garden store that it was homozygous (pure-breeding) but you are not completely sure. Show how you can find out.

Two genes are found in a chameleon, one for camouflage (dull colors dominant to vibrant colors) and another for muscle strength (strong dominant to weak), which seem to follow basic Mendelian inheritance patterns, To determine if they are linked, you set up a testcross and got the following results: Phenotype Number of Progeny Dull colors; Strong 98 Dull colors; Weak 76 Vibrant colors; Strong 72 Vibrant colors; Weak 105 Did you start this experiment with the genes in coupling or repulsion? O Coupling O Repulsion O Cannot determine with this information

In pea plants yellow seed color, (GG) and round seed shape (WW) seeds are dominant traits, while green color or (gg) wrinkled shape (ww) seeds are recessive traits. You cross a pure breeding plant with yellow wrinkled seeds to a pure breeding plant with green round seeds to generate F1s. When you perform a reciprocal cross you get the same results. You take an F1 male and an F1 female and generate an F2 population. Of all the F2 offspring you count 18 that have yellow wrinkled seeds. Based on this information, how many F2 offspring do you expect to display only dominant traits? a) 72 b) 54 c) 18 d) 24 e) 6

Mendel also studied tall and short varieties of pea plants. When he crossed tall x short plants together, the F1were tall. The tall F1 plants were self-hybridized to produce the F2. What proportion of phenotypes would be expected in the F2? 1:2:1 tall:intermediate:short 3:1 tall:short 1:1 tall:short 3:1 short:tall 1:2:1 intermediate:tall:short

In rabbits, black hair is due to a dominant allele B and brown hair to its recessive allele b.  Short hair (H) is dominant to long hair (h).  In a cross between a homozygous black, longhaired rabbit and a brown, homozygous shorthaired one, what would the F1 generation look like?  If you did not know the genotype of an F1 rabbit, you could determine its genotype by a test cross in which it is crossed with an animal with which phenotype AND genotype If you carried out this test cross, what phenotypes and in what ratio would you expect? What phenotypes in what ratio would be expected in the F2 generation?

You are studying the genes that affect wing size in butterflies. You cross two true-breeding strains (one strain with extremely large wings crossed to one strain with extremely small wings), and then cross the F1 butterflies. You measure 320 F2 butterflies and find that 5 are the same size as the extremely small parent, 5 are the same size as the extremely large parent, and the rest show a range of body sizes between these extremes. How many genes do you estimate contribute to wing size in butterflies?
